If the power supply module needs a high amount of braking power when it
comes as standard built−in unit or in push−through technique design (ECSEE /
ECSDE), an external and more powerful brake resistor can be connected instead
of the internal brake resistor.
A power supply module in cold plate technique design (ECSCE) is not provided
with an internal brake resistor so that this version always requires an external
brake resistor (Rbext).
Connect the brake resistor to X22/BR1 and X22/+UG.

Connect the thermal contact (NC contact) of the external brake resistor to
ƒ
X6/T1 and X6/T2.
104
Always operate the ECS power supply modules with a brake
resistor.
A parallel wiring of internal and external brake resistor is not
permissible!
Implement the thermal contact of the brake resistor into the
system monitoring so that the mains supply of the power supply
module will be switched off in case the brake resistor will be
overheated.
Read the documentation for the external brake resistor. Observe
the safety instructions contained therein.
